Title: Mirror detection method and mirror detection circuit
Inventor: ARIUMI HIROKO
IPC: G11B7/085
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To make performable mirror detection stably for both CD and DVD having different OFF track level/ON track level ratio of mirror signal being generated depending on the presence/absence of a track when an optical pickup traverses a disc due to difference of track pitch. SOLUTION: In order to detect the mirror signal of an RF signal SRF, the RF signal SRF is subjected to a bottom detection, respectively, through high speed and low speed bottom detection circuits 1, 2 to produce signals S1, S2 which are then inputted to a variable gain amplifier type subtractor 3 to perform a subtraction and only a mirror signal S4 is taken out. A DVD/CD control circuit 21 switches the gain depending on a disc such that the signal S3 has a substantially equal output amplitude for the DVD and CD. Output amplitude of the substractor 3 is detected by a maximum/minimum value detection circuit 22 and an operating unit 23 generates an intermediate value signal S4. A stabilized mirror detection signal S5 can be outputted by comparing the output S3 from the substractor 3 with a comparison point, i.e., the voltage of the signal S4.

IPC: H01S5/00
Filed: 1983-04-26
Abstract: PURPOSE:To prevent the generation of a current route on the side surface and enable to avoid the deterioration of reliability by contriving that a high resistant layer separates from an oscillation region and the depth including the side surface exceeds a P-N junction surface. CONSTITUTION:A metal serving as the mask for proton irradiation is vapor- deposited on a wave guide structure completed wafer by the combination of the processes for photoresist and liftoff, so as to remain in stripe form 61 more widely than a stripe width on the surface immediately on the stripe of the oscillation region with said stripe as the center. At this time, the distance from a proton irradiated layer 32 to the oscillation region 19 is needed at least 15mum or more. Next, the high resistant layer 32 is so formed as to reach a depth exceeding the P-N junction surface by performing proton irradiation. Thereafter, the masking metal 61 is removed, and a mounting electrode 18 is vapor-deposited. Then, the substrate is polished to a required thickness, and a bonding electrode is vapor-deposited on the back surface, thus completing the wafer. Finally, the wafer is cleft at the right angle to the oscillation region, and afterwards pellets are separated at the center of the high resistant layer 32.

IPC: G06F17/50
Filed: 1992-02-25
Abstract: PURPOSE:To synthesize a logical circuit in which the number of wirings, the number of gates, and especially a delay value are minimized. CONSTITUTION:A step 104 and a step 114 are operated as necessary. A logical cell in a logic circuit being the object of a logical synthesis is expanded to a basic logical cell (step 108).

IPC: G01M11/02
Filed: 1989-03-24
Abstract: PURPOSE:To decrease noises caused by irregularities in moving speed and vibration of a total reflecting mirror and to improve S/N by detecting interference signal generated in a modulating means within the interference intensity of synthesized light in a narrow band. CONSTITUTION:As a splitting and synthesizing means, a fiber-shaped 3-dB coupler 3 is used. As an adjusting means, a cylindrical electrostriction vibrator 16 which is wound around a piece of fiber on the emitting side of the coupler 3 is used. Then, a phase-modulated voltage which is periodically changed in a triangular wave pattern is applied. Thus, linear-phase change alphat (alpha is a constant, and t is time) is imparted to reference light and the reflected light from a light guide 7 to be measured. An optical detector 10 detects the interference signal which is modulated with a modulating means and has the frequency of alpha/2pi in a narrow band based on the signal obtained by receiving and detecting the synthesized light. At this time, the reference light is obtained by moving a total reflecting mirror 5a which is optically coupled with one end of the fiber on the emitting side of the coupler 3 step by step. Therefore, irregular noises due to the irregularities and the like in moving speed of the total reflecting mirror 5a is decreased, and S/N is improved.

Title: Electromagnetic rotation detecting device
Inventor: NAKANO TOMOHIKO
IPC: G01D5/245
Filed: 1986-03-31
Abstract: PURPOSE:To increase a signal level by increasing the facing area between the ruggedness part of a rotary member and the front end part of a magnetic core. CONSTITUTION:Magnetic flux produced by a permanent magnet 21 forms a magnetic path from, for example, a core 22 to a rotor 13. At this time, when the rotor 13 rotates, a gap in the magnetic path varies because of the ruggedness part 13a. The resistance of the magnetic path also varies correspondingly and the magnetic flux density varies. Therefore, magnetic flux cross-linked with a coil 23 varies, and consequently a sine wave AC signal is generated at the coil 23. In this case, the front end part 22a of the core 22 and the ruggedness part 13a of the rotor 13 are both formed at a specific angle, so the facing area between the both increases and the signal level, therefore, increases.

Abstract: PURPOSE:To absorb a force generated on the interface of a rotary polygon mirror and an insertion guide member and to hold the internal diameter of the rotary polygon mirror concentric with its rotary shaft by forming radial grooves in the member for the insertion and guidance of the rotary polygon mirror and making the external diameter of the rotary polygon mirror insertion guide member larger than the internal diameter of the center hole of the rotary polygon mirror. CONSTITUTION:A hill-shaped part 12 is projected from the top surface 11 of a hub 10 as the insertion guide member for the rotary polygon mirror 8 and the radial groves 14 are formed inside the hill-shaped part. The hub 10 can freely be fitting onto the rotary shaft 2 because of the hole part 13 formed in it. The external diameter alphaof the hill-shapped part 12 of the hub 10 which guides the rotary polygon mirror is made larger than the internal diameter of the fitting hole 9 of the rotary polygon mirror 8. Consequently, deformation or deflection delta caused by the difference between the internal diameter of the hole of the rotary polygon mirror 8 and the external diameter alpha of the hub 10 is absorbed by the radial grooves 14 in the hill-shaped part 10 and the internal diameter of the hole of the rotary polygon mirror 8 is held concen tric with the rotary shaft 1, so that the mirror surfaces of the rotary polygon mirror 8 are hole at an equal distance from the center of the rotary shaft 2.

Abstract: PURPOSE: To prevent the deterioration in the damper effect by means of an oil film formed in a clearance between a mobile disc and a fixed disc arranged horizontal.  
     CONSTITUTION: The first magnet S is imbedded on the inner bottom of a casing 1. Facing this magnet S, arranged is a mobile disc 14 having a small-diameter projection 13 having the second magnet N imbedded. When a pivot shaft 19 rotates, a lubricant flows through a concave section between a spherical body 18 and a bearing seat 17 while flowing into a clearnace between the mobile disc 14 and a  fixed disc 20 to form an oil film. Consequently, the magnets N and S applies a centripetal force to ensure smooth rotation of the pivot shaft 19. As the mobile disc 14  and the fixed disc 20 are both flat and arranged parallel, an oil film of the lubricant  is present in a fine clearance between both discs thereby eliminating the generation  of bubbles.
